Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If additional access points or relay nodes are introduced to extend wireless coverage, then the coverage area is improved, but latency increases and network complexity increases
Solution Approach 1:
The patent implements dynamic role reassignment where access points can switch between backbone and access roles based on real-time network conditions. This dynamic adaptation allows the system to optimize latency by having nodes assume roles that minimize transmission paths, while still maintaining extended coverage through the mesh topology.
Solution Approach 2:
The system changes operational parameters by switching nodes between different roles (backbone vs. access) and adjusting transmission parameters based on telemetry data. This allows optimization of latency and throughput while maintaining coverage, resolving the contradiction between extended coverage and low latency.
2Area of stationary object
If additional access points or relay nodes are introduced to extend wireless coverage, then the coverage area is improved, but network complexity increases
Solution Approach 1:
Each access point in the mesh network is designed to perform multiple functions - it can operate as either a backbone node or an access node depending on network conditions. This multi-functionality reduces overall network complexity by eliminating the need for specialized nodes, while still enabling extended coverage through the flexible topology.
Solution Approach 2:
The system uses telemetry information feedback to automatically adjust node roles and network configuration. This closed-loop control simplifies network management by automating complexity reduction, allowing the system to maintain optimal performance with extended coverage without manual intervention.
3Ease of operation
If a main node is used to orchestrate network communication, then network control is improved, but reliability deteriorates due to single point of failure
Solution Approach 1:
The patent segments the centralized control function into distributed control across multiple nodes. Each access point can independently perform role reassignment and network orchestration based on local telemetry data, eliminating the single point of failure while maintaining coordinated network control through the mesh topology.
Solution Approach 2:
The system implements self-service capability where access points autonomously monitor their own performance through telemetry and make decisions about role reassignment without requiring a central controller. This self-service approach improves reliability by removing the single point of failure while maintaining effective network control through distributed intelligence.
4Ease of manufacture
If conventional Wi-Fi protocols are used, then ease of deployment is improved, but throughput and performance are limited
Solution Approach 1:
The patent extends conventional Wi-Fi deployment ease by adding dynamic role reassignment capability. Access points can automatically switch between backbone and access roles based on network conditions, maintaining the simplicity of Wi-Fi deployment while dramatically improving throughput and performance through optimized network topology and traffic routing.
